Today IDE were upgraded to VS for Mac 7.5 (build 1254) and my project stops to compile because of following error:
Internal compiler error: The method or operation is not implemented. (CS0584)
This error is caused by following expression:
Build > General > C# Language Version is set to "Default".
Does anybody have the same issue with Encoding.UTF8.GetString() method and latest stable version of VS for Mac ?
PS I checked above error at new test project. The minimal example to reproduce this error is:
var test = Encoding.UTF8.GetString(Convert.FromBase64String("dGVzdA=="));
